In a new paper published in Monthly Notices of the Royal Astronomical Society scientists explain that they have confirmed the presence of two clouds of dust that are orbiting Earth at around the same distance as our Moon. The discovery is confirmation of work that stretches back decades to the early 1960s when the clouds were first spotted.
The presence of the dust clouds has been extremely difficult to prove because they are so faint. They are collections of extremely tiny particles stretched over an enormous area that dwarves even Earth itself, but they are definitely there.
These “moons,” as some are calling them, obviously are not actually moons as you would normally think of them. They are just huge, thin clouds of dust that are trapped in Earth’s orbit. They are many times the size of Earth itself, but you can not see them with the naked eye because not enough light bounces off of the tiny particles and finds its way to our planet.
The big puffs of space dust have been named “Kordylewski clouds”, which is a node to astronomer Kazimierz Kordylewski, the first person who claimed to have actually spotted them back in 1
961. Even after that discovery, the existence of the clouds was debated, but they have now been detected with
“The Kordylewski clouds are two of the toughest objects to find, and though they are as close to Earth as the moon, are largely overlooked by researchers in astronomy,” Judit Slíz-Balogh, co-author of the new study, said in a statement. “It is intriguing to confirm that our planet has dusty pseudo satellites in the orbit next to our lunar neighbor.”
The existence of the dust clouds does not mean a lot to you and I, but it does shed some light on the dynamics of Earth orbit. De steder hvor støvet er fanget, er Larange-punkter, og forskere mener at steder som disse kan være de mest ideelle steder for placering af rumstationer eller satellitter til langvarig brug.
